| Sumario: | The organic fertilizer is being treated as a form of nutrition for plants, reducing the application of chemical fertilizers. Thus, the objective was to verify the extraction of nutrients, seed quality, soil chemical properties, development and yield of winter beans and corn rotation, obtained from the organic fertilizer and mineral. The study was conducted in the experimental area UNESP - Ilha Solteira design was completely randomized blocks in 4 x 2 factorial scheme with four replications in a Oxisol. The treatments consisted of four doses of the compound resulting from waste from the production processes of agro-industries (0, 2, 4, 6 t ha -1 ) and two treatments with chemical fertilizers (control and half the recommended dose for dry beans of 125 kg ha -1 4-30-10). There was neither effect of the organic fertilization on the yield components of bean, no residual effect on corn. However, the application of organic fertilizer changed the Ca and Mg in the bean crop, besides the P, S and Ca in the corn. For soil chemical attributes the increased organic compound on soil nutrient content, especially raising the level of phosphorus and potassium, but decreases calcium exchangeable with increasing doses in the area cultivated in no-tillage system |
